PCU Hardware Diagnostics
Intended use
The PCU hardware supports the diagnostics of important system components via an
integrated "safecard", which is designated as a Safecard-On-Motherboard (SOM).
These diagnostic functions are only evaluated by systems with HMI Advanced. The fault
statuses of the hardware are reported in the form of alarms via the operator interface of HMI
Advanced. This allows for visualization of the data in HMI Advanced and external evaluation.
Monitored Parameters
The following physical parameters of the PCU hardware are monitored:
● CPU temperature
● Housing temperature
● I/O chip temperature
● Speed of the two housing fans
● S.M.A.R.T - status of the hard disk
Logging faults
The PCU hardware monitor logs all hardware faults in the Windows event log so that the
faults can be output even without installing an HMI application.
The alarms are output in the log under "Control Panel" → "Administrative Tools" → "Event
Viewer".
